For those needing to travel outside the limits of the Metrolink system, Amtrak provides direct service along the California coast and connecting service (via Los Angeles’ Union Station) to destinations through the country. Amtrak’s Pacific Surfliner makes 12 trips daily between San Luis Obispo and San Diego, with service to the Irvine Station and the Santa Ana Station. The train makes stops along the coast in San Luis Obispo, Santa Barbara and Ventura counties; in the San Fernando Valley; at Union Station in downtown Los Angeles; and at several Orange County locations before continuing on to San Diego. Amtrak is an enjoyable way to travel, with comfortable seating, an onboard cafe, scenic views and a business class featuring electrical outlets and complimentary beverage service. Bicycles and surfboards are allowed on most Pacific Surfliner trains. One-way tickets on this route cost between $7.50 and $62.00 depending on the distance traveled.
